In recent years, we have seen something of a paradigm shift in the air purifier market. It used to be that stalwarts like Honeywell and Levoit dominated the market without many alternatives. But today, companies like Blueair and Molekule are shaking up the industry and providing consumers with more innovative options. Today we are going to be taking a look at these two companies and some of their products. This Molekule vs Blueair and Blue Pure comparison will explain the differences and benefits of the Blueair Classic 605 vs Blue Pure 211+ vs Moleklue vs Molekule mini.
Blueair vs. Molekule Comparison Ratings
Molekule vs. Blueair and Blue Pure Reviews
The Blue Pure 211+ is our favorite air purifier on the list. It’s very quiet and does not draw a lot of power, it has a very streamlined design, and the pre-filter comes in a variety of colors. This particular model is rated to purify air in rooms of up to 540 square feet and does so quickly and quietly. It also features a washable outer mesh pre-filter for trapping larger debris and is very popular for those who live in areas with wildfire smoke.
With it’s one button control, you simply tap the white circle on the front and it turns on, while each subsequent tap raises the fan level from low-medium-high. With these easy-to-use and intuitive controls, anyone can operate this machine. The only drawback is if you have pets that sometimes walk into it, shutting it off!
When it is time to change the filter, the ring around the light changes color to let you know. The filters within are collapsable, which makes them easy to store and to replace you simply lift off the top half of the device and pull out the filter.
At high the sound is loud but still a reasonable 51dB. Running at low it is hardly noticeable and great for overnight use.
With its outer pre-filter that comes in a variety of colors, you can dress this filter up to fit your aesthetic. Easily removable, simply wash it, let it dry and put it back on. Within the Blue Air 211+ is a collapsable filter that uses electrostatic filtration to remove up to 99.97% of airborne particles, with a layer of activated carbon to filter out smelly household odors.
Very popular in areas with wildfires, the Blue Air 211+ filters out the contaminants from smoke, pets, cooking, and harmful VOCs.
- Up to 5 air exchanges per hour
- Quietly runs at 31 decibels on its lowest setting
- Eliminates most pollutants that cause sinus irritation and allergy issues
- A variety of colored pre-filters to choose from
- One of Wirecutters top-air purifier picks
- Filter replacements are expensive
- Not WIFI capable
Although the design on the BlueAir Classic 650 is not as modern as the other models on our list, looking more like an old computer tower than anything else, it sure does a great job at filtration!
This model features an activated coconut carbon filter that naturally eliminates odors and gaseous pollutants in the air. A great choice for those with seasonal allergies, asthma, and hay fever, the HEPASilent technology within this device creates an electrostatic charge that attaches to contaminants and filters them out.
With a certified clean air delivery rate of 500 cubit feet per minute, it goes through all the air in your room 5 times per hour. This provides maximum relief from airborne particles, quickly giving you clean air that will have you breathing easy in no time.
The BlueAir Classic 650 is WIFI capable, so you can control it, and access all the features, via your smartphone and the mobile app. From there, you will able to see indoor air-quality reports in real time. You will also be able to use your phone as a remote control and access the functions from anywhere within your home. With auto-mode on, the device will adjust the fan depending on the level of pollutants it detects in the air, making it a very hands-free device.
This air purifier works great in large rooms, upwards of 800 square feet, making it perfect for cleaning an entire studio apartment and any room in the house.
- Smart air quality sensor
- Good at eliminating odors
- Natural carbon filter
- Perfect for cleaning the air of wildfire pollution
- Very quiet
- Great customer service
- Upward facing fan
- Light leaks so not great for overnight use in a bedroom
This is the flagship of the Molekule line of air purifiers and with its sleek design and leather strap it will add to the charm of any room its in. While it does have a more modern design than the Blueair Classic, it has limited functions and is not quite as quick at cleaning the air.
This model features a dual filtration system: a pre-filter to capture large debris like hair and dust, and then the PECO (Photo Electrochemical Oxidation) filter that breaks down smaller particles and pollutants. Great for eliminating viruses VOCs, allergens, bacteria, and mold in rooms up to 600 square feet. It operates on 3 fan speeds with the lowest setting running at 41dB, making it a great choice for any room of the house.
Like the Blueair Classic, the Molecule Air is WIFI compatible, but it lacks any features other than the ability to control the fan. Connecting it to WIFI will allow you to control the device from anywhere in your home, or you can use the one-touch display for changing the fan speeds. It is much more portable than either of the Blueair models; when you want to move it from room to room, simply grab the leather strap and go.
The biggest difference between the Molekule and Blueair models is that rather than collect the pollutants within the filters, it destroys them. Using nanoparticle-coated filter layers, these react to light and destroy any contaminants. Utilizing low-energy UV-A light, this starts a series of chemical reactions on the surface of the filter that generate hydroxyl radicals. These are what destroy any organic airborne pollutants!
- Effective for destroying pollutants rather than just collecting
- Makes air cleaner and fresher
- Stylish design
- Easy to transport
- No air-quality measurements
- Auto-speed does not auto adjust
We loved the look of the Molekule air purifier and that it had 360-degree air intake and outtake. What we didnt love was that it seemed to take a while for the to become as clean ‘feeling’ as the Blueair models. Even with the fan speed maxed out, it doesn’t seem to pull in or expel nearly as much air, though after 2 days of use our allergies symptoms did go away and the air felt much fresher than outside. The ability to change the settings from your phone is a plus, but the app lacks any other features, such as air-quality measurements. Although it lacks in features and power when compared to Blueair, this is a great air purifier for a small space and if design aesthetic is a factor, this would be a good choice.
This smaller Molekule model was designed to work in rooms up to 250 square feet in size and while it may take a bit longer to clean the air, it is very portable and can sit just about anywhere.
The Molekule Mini air purifier features just the one PECO filter, but weighs only 11 pounds and stands just 12 inches high. It has 5 fan speeds and is a great option for smaller rooms and studio apartments, or to sit alongside your office desk. Unlike the boxy Blueair models, the rounded shape gives a more discreet appearance.
Like the other Molekule air purifier on our list, it is WIFI compatible so you can change the fan speeds from your smart phone. Unfortunately, thats about all you can do. You can also use the one-touch interface if you are sitting right next to it.
The natural felt handle and small size make for easy portability, which is the main feature of this air purifier, especially compared to the bulkier Blueair Models. It will clean the air, but unless you are in a smaller room, it may take quite a while. It does have a whisper-quiet mode, but compared to the Blueair 211+ which is also very quiet, it can’t compete in power.
It has a 360-degree air intake and exhaust, which help with air circulation. It also means that theres no chance of blocking the filters if you place it up against a wall.
- Can easily be carried from room to room
- Advanced filtering technology
- Great for studios and dorms
- Inefficient in rooms larger than 250 square feet
- Can only change fan speed from the app, limited features
- No independent remote control
- Expensive filter replacements
Blueair vs. Molekule Company Comparison
Blueair products are sold in 60 countries around the world. They are a Swedish company that is part of the Unilever group of brands. They are a company that takes a lot of pride in the sleek design of their products. After using their air purifiers for a few months, we noticed an improvement in overall air quality. It is apparent that they have gone to great lengths to ensure both high quality design and air filtration in their products.
Molekule was launched in 2014 after decades of work and research went into developing their proprietary photo electrochemical oxidation technology. They are a relatively young company but it is clear that they are one dedicated to innovation and changing the quality of indoor air for the better.
After reviewing products from both of these companies, we must say that we were impressed with both. While Molekule is changing the way indoor air is treated, Blueair is marrying sophisticated design and powerful air filtration.
It was also nice that we could connect the Blueair to Alexa and control it by voice. We think both of these companies deserve your attention – especially if you are looking for an alternative to the industry titans like Honeywell and Levoit.
If you are interested in ease of use and convenience, then check out the BlueAir family of air purifiers. If HEPA filter air purifiers haven’t helped you in the past, then you should definitely check out any of the Molekule air purifiers.
